***** - Nedbank dont care

On 13/4/2017 i was on duty. At about 14:12 i received a call from telephone no. + ********** 2967. The caller alleged to be an employee of Nedbank assisting with redeeming of greenbacks of which i have never heard about. She had all my detail e.g. ID No, residentail address, credit card number, the etiquette of Nedbank employees where you are told 'the calls are recorded...' and all i had to do was to confirm my details which i did. Five minutes later at about 14;17 whilst busy at work I received an sms from Nedbank confirming a purchase or transaction to the value of R14000.00 from WWW.EASYPAY.CO.ZA. Suspection ***** i drove quickly to the Nedbank branch at Malvern/Queensburg Durban for assistance which took me about 15 minutes. Indeed the bank confirmed a ********** transaction to the given value above. I was offered Dispute form to fill which i did. I had the same credit card in my possession all the time and gave no one any authority to use it. I am also unaware of what was purchased. On 21/04/2017 I received a letter from Nedbank card dispute resolution services advising me to refer the same to the supplier which left me more confused and frustrated. At the moment i am paying my installment but it is not enough cause there are huge charges. I receive undated calls from collections department with no assistance. I need help or someone who will listen and come up with the solution.
